@@davidrickey3776 Found out it's a green wire in the upfitter harness under the dash. "The headlamp flashing module is activated by the application of 12 volts to a dark green wire in the upfitter harness connector labeled 6J3. When activated, the headlamp high beams and the high beam instrument cluster indicator will flash alternately at 3.0 flashes per second. When the flashing module is turned on, the module sends a signal to the BCM which alternately flashes the stop lamps and backup lamps at the same flash rate as the headlamps. Depressing the brake pedal will override the stop lamp flashing and placing the transmission in Reverse will override the backup lamps flashing"
Once the flasher is installed how do you activate it?
I am wondering same thing
